I actucally agree with Abwayax.There are other ways to wis your forum friends goodbye.PM's are one of these.The main purpose of posting a goodbye thread is to get people to be all tear jerky about your leaving. Its kinda narcissistic when you think of it, grabing for attention as a last action on a forum.Now a staff step down thread can sometimes be useful, but that doesn't belong here.
